sharpening end mills by hand.

[Sunset Machine]

Grind the bad end off, but make it look like an endmill. Little strips of paper will help square things up. Endmill in the spindle, paper strips on the table, then quill down until contact is made. A little tugging on the strips will show the long one(s) real quick. Watching the angles, use a stone while still in the spindle. Repeat as needed.

I bet you guys put split points on your drills by hand too. After the normal sharpening, I'll touch the backside against the wheel until it sparks a little, then slide the bit to the left until the sparks meet the chisel point. Easy peasy.
